[UI] "Copy template" for nodegroup doesn't copy None for floating IP pool

[Andrew Lazarev]

Steps to repro:
1. Create nodegroup template with "Do not assign floating IP"
2. Click "copy template"
3. See that "Floating IP" field is filled with some pool

So, looks like we should copy None values too (to make None default value for dropdowns).
